Laboratory Work No. 6 String Checker In this laboratory work, the student should implement in C language the string-checker algorithm given below: Repeat Get a symbol from the user If symbol is an alphabet, then If it is a lower-case alphabet, then Convert it to upper case End-if Insert it to the queue Else-if symbol is a digit, then Discard it Else-if symbol is a punctuator, then Discard it Else-if symbol is a white-space character, then Insert a space character to the queue Else / is an unrecognized character */ Discard it End-if Until symbol is different than the newline character (enter key) While queue is not empty, do Remove a character from the queue Display it on the screen End-while Note that you should translate the pseudocode one-to-one into C statements. Laboratory Work No. 8 Linked Queue In this laboratory work, the student should implement the string-checker algorithm (see Lab Work No. 6) using the linked- queue structure discussed in Lecture-8
